this summer i changed alternator and belt, now when i start the 02 elentra, the belt squeals until i rev it to about 2000 rpm (and does not squeal as i am driving), the belt is tight and alternator is working correctly. I already tried spraying belt with belt dressing, it stopped the squeal for only a couple days, any other suggestions???, thanx in advance
Since you've put on belt dressing, you'll need to replace the belt and clean the crankshaft, alternator, and water pump pulleys of the goop.
The alternator belt on this engine needs to be tensioned much tighter than most belts to prevent squeal. If you can flex the belt even a little with light pressure, it's too loose.
